Heart Lake

Heart Lake (Skagit County) is one of five Fidalgo Island lakes regularly sampled by IWS (Campbell, Erie, Heart, Pass, and Whistle). Located off Heart Lake Rd., this small lake is indeed shaped like a heart. Within walking distance of the public access are numerous trails, some designed for mountain bikes and others for horses. The lake experiences frequent blue-green algae blooms, which may produce dangerous toxins, so avoid water contact if there are warning signs posted.
